Abstract: A drive member and a rotation member are rotatable with respect to a housing. A stop member is rotationally locked with the housing. Clutches unidirectionally rotationally engage the drive member with the rotation member and with the stop member when a unit is attached to the housing. A separating member is disposed between the rotation member and the stop member. The separating member causes a separation of the rotation member, the drive member and the stop member when the unit is removed. A coupling feature of the separating member is provided to engage the unit and to move the separating member when the unit is being attached to the housing or is being removed.
